METHOD FOR PRODUCING A THERMO FORMED PART, COMPRISING A FOLDING OPERATION EXECUTED WITH THE MOULD CLOSED, AND MOULD FOR APPLYING THIS METHOD |
摘要 |
A method for producing a thermo formed part comprises the steps of: closing in a mould a heated sheet (L) made of thermoplastic material in such a manner as to deform the latter, then cooling it inside the mould until complete consolidation is achieved; during cooling, cutting the sheet along at least one edge portion (E) thereof, this cutting operation causing a bending of the edge portion against an abutment surface (1s) in the mould; and removing the upper half-mould from the lower half-mould once the consolidation of the deformed sheet has been attained. During the cooling of the sheet inside the mould, subsequently to the cutting operation a folding operation is performed, this folding operation comprising the steps of: moving the abutment surface away from the edge portion of the sheet, and operating on the edge portion in such a manner as to resume its bending towards a support surface (2s) of the sheet in the mould. |
